Answer:
a. Ed/eD
b. RF=0.12
Explanation:
The alleles for genes D/d and E/e are:
- D_: only on neck spikes
- dd: along back spikes
- E_: long spikes
- ee: short spikes
After testcrossing a double heterozygote (DdEe x ddee) there are 4 types of offspring, two of them much more abundant than the other two. The homozygous recessive parent can only produce <em>ed</em> gametes, so the phenotypes of the offspring depend on the gametes that the double heterozygous parent produced.
The offspring was:
- Ed/ed 79
- ed/ed 12
- ED/ed 10
- eD/ed 76
Total: 177
a) This result suggests that the genes are linked. Since recombination is a rare event, the most abundant phenotypes always come from the parental gametes, and the least abundant come from the recombinant gametes.
<u>Therefore, the genotype of the doube heterozygote parent was </u><u><em>Ed/eD</em></u><u>.</u>
b) Recombination frequency (RF) = Recombinants / Total
RF = (12+10)/177
<u>RF = 0.12</u>
Answer:
the answer is all of these
Hepa filters can efficiently remove microbes from the air (Option a is correct).
<h3>What are Hepa filters?</h3>
Hepa filters, i.e., high-efficiency particulate air filters, are used to separate microorganisms from the air.
These filters (Hepa filters) eliminate over 99% of microorganisms such as bacteria, dust and pollen particles having a size higher than 0.3µm.
In conclusion, Hepa filters can efficiently remove microbes from the air (Option a is correct).

The difference between the "Question" and the "Hypothesis" is that a hypothesis is what you believe is the answer to the question based off of limited evidence while the question is just a regular question e.x. (for question) "Why is the water moving to the south?"
then using whatever evidence they will have they would do a hypothesis e.x. (for hypothesis) I believe the water is moving south due to the wind coming down from the north... or due to a current.
